Weeds yet to reach their full potential as invaders after centuries of changeWeeds in the UK are still evolving hundreds of years after their introduction and are unlikely to have yet reached their full potential as invaders, UNSW Australia scientists have discovered.http://phys.org/news334922044.html

BiologyFri, 28 Feb 2014 11:10:08 ESTnews312806545Tiger lily heights controlled with flurprimidol preplant bulb soaksGrowers and retailers of perennial greenhouse and landscape plants are often challenged by the sheer height of some consumer favorites. While plant height can enhance a plant's versatility and appeal in gardens and landscapes, transporting taller plants from growers to retail or wholesale outlets, and then on to their ultimate destinations can be a challenge. Colorful, summer-flowering, bulbous perennials such as lilies are commonly used as ornamental landscape plants, cut flowers, and potted plants, but their structure makes them top heavy and limits their production and transportability. Jared Barnes, Brian Whipker, Wayne Buhler, and Ingram McCall published a study in HortTechnology that can offer solutions to this weighty issue.http://phys.org/news312554365.html

Although PGRs can be applied using a variety of methods, most common applications are foliar sprays or substrate "drenches". Research has shown that drenches provide more uniform results and increase the duration of effectiveness compared with sprays, but the efficacy of drenches can be affected by factors such as the amount of solution applied and the substrate components used.http://phys.org/news227963286.html
